The unique connectivity pattern of a brain region determines the type of information available to it, and hence influences its function. Defining these patterns enhances our knowledge of human brain architecture and function. Non-invasive in vivo definition of brain connectivity patterns complements functional imaging and provides new understanding of disorders associated with developmental or regional alterations of brain connectivity. There are extensions to this approach to clinically important issues. As an example, brain connectivity problems are important in developmental and acquired brain disorders.
Researchers working within the University of Oxford Clinical Neurology Department have developed a technique that is able to provide non-invasive identification of boundaries between major nuclei in a patient undergoing surgery, thereby improving both targeting accuracy and outcomes. The invention relates to mapping the connectivity of the brain’s nervous system in a human, and uses imaging data derived from magnetic resonance imaging. New computer methods derive the anatomical connectivity patterns, and analyse the structure of the nervous system.
Testing the hypothesis that changes in fronto-thalamic circuitry i.e. thalamic dysfunction is a factor in schizophrenia becomes a reality using this methodology. Impairments in cortico-cortical connectivity are found in individuals with learning disabilities. The new method allows a quantitative approach to the differences so that actual variations in learning abilities and performance can be determined. At present localisation in stereotactic neurosurgery or deep brain stimulation of specific thalamic nuclei in movement disorders remains difficult. This approach to grey matter segmentation has the potential to improve targeting accuracy and outcomes.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
